To all whom it may concerm- Be it known that I, FRANKLIN P. CIRCLE, ofthe city of Springfield, county of Clark, and State of Ohio, haveinvented certain new and useful Improvements in Hubs for Vehicles, ofwhich the following is a specification.

This invention relates to hubs for vehicles, &c., the object of theinvention being to construct a metallic hub having a spoke-flange in onepiece, and to provide the same with an elastic filling or core extendingfrom a point near one end to and flush With the opposite end of the hub,the said filling having a tapered opening corresponding to the taper ofthe boxi7 for the axle'spindle. Another object of the invention is'toextend the spokereceiving mortises, or a portion of them, en tirelythrough the hub metal, whereby all or a portion of the said spokes maybear against the elastic filling of the hub.

The invention consists in a metallic hub 'for vehicles,constructed inone piece and having a central spoke-receiving fiange, the mortises ofwhich have slightly-beveled edges, the said hub being provided with anelastic filling or core extending from a point near one end to and flushwith the opposite end of said hub, substantially as and for the purposehereinafter described.

It also consists in certain details of construction, hereinafterdescribed.

Figure 1 of the drawings represents in central longitudinal section avehicle-hub as coustructed in accordance with ny invention; and Fig. 2,a vertical cross-section on dotted line x x, Fig. 1, of the same.

The hub A, which may be of any usual shape and metal, will be cast inone piece With the fiange B, which extends entirely around it, the saidfiange projecting from the main body of the hub, as usual with patenthubs77 having a central fiange for receiving the spokes. The fiange B isprovided with mortises to receive the spokes C, said mortises beingslightly beveled at their upper end, as shown at a, Fig. 2, to obviatethe entrance of water, and, as shown, some of said spoke-receivingmortises extend entirely through the metal to allow one or more of thespokes tobe driven through and into an-elastic filling, D. Thisfilling,which is made of rubber, is in one piece,and extends from theforward shoulder sol;

of the hub back to and flush with the oppo-` 1 site end, the saidfilling being provided With f i a central hole oorresponding to theshape of v the box E, in which the spindle of the axle revolves.practice made slightly of larger diameter than the internal diameter ofthe hub, thesaid filling being forced into the hub by any suitable Thebox E for the axle-spindle is and may be of any usual construction.

By driving a portion of the spokes C into the elastic filling D itprevents any possbility of the filling turning.

I claim- The metallic hub A, cast in one piece and provided with thefianges B, having bevely edged mortises, as described, a portion of saidi mortisespreferablyexteuding entirely through the metal of the hub, incombination With therubber filling D, (provided with the axle-box andextending substantially from one to the other end of the hub,substantially as and for the purpose described. l' i In Witness whereofI have hereunto set my hand and seal, at Springfield, Ohio, this lst dayof December, A.
